Öğe Aim: Background: The aim of this study is to compare the microvessel densities of different normal gastric regions and to determine the effects of sleeve gastrectomy on the microvessel density of tissues alongside the remnant stomach. Material and Methods: Twenty male Wistar albino rats were divided into two groups. Rats in the control group were immediately sleeve gastrectomized under anesthesia and a wedge resection of the esophagogastric junction (EGJ), the fundus, corpus and antral gastric regions was performed, before sacrifice. Meanwhile, rats in the experiment group also underwent sleeve gastrectomy but were not sacrificed until the 5th postoperative day. At this point, gastric tissues alongside the sleeve gastrectomy area were then wedge-resected. The microvessel densities of these two groups were evaluated and compared. Results: When comparing distinctive gastric regions within the control group, the microvessel density of the esophagogastric junction was found to be less than in the corpus or fundus (20.04±4.45; 36.28±9.98, 39.4±9.57; p <0.01). When comparing the control and experiment groups, No significant difference in the microvessel density of the esophagogastric junction was found (20.04 ± 4.45, 24.63 ± 8.91, p> 0.05). The sleeve gastrectomy also had no significant effect on the microvessel densities at the esophagogastric junction or corpus (24.63±8.91, 22.24±7,63; p> 0.05). Conclusion: The esophagogastric junction has a lower microvessel density than the corpus in a normal stomach. Sleeve gastrectomy has no adverse effect on the microvessel density of the esophagogastric junction(2018) Sargin, Mehmet; Uluer, Mehmet SelcukAim: Lumbar spine surgeries can be performed under general anesthesia or spinal anesthesia. We aimed to compare the effects of spinal and general anesthesia on intraoperative bleeding in patients undergoing lumbar disc surgery. Material and Methods: Fifty patients scheduled to undergo elective single-level lumbar discectomy under spinal or general anesthesia were studied. The amount of blood loss was calculated by subtracting the wash solutions from the amount in the aspirator reservoir and evaluating bleeding in the gauze used throughout the operation. The time between the first incision and the final suture was evaluated as the surgical time.Patients’demographic data, duration of surgery, amount of fluid given intraoperatively, intraoperative hemodynamic data, intraoperative blood loss, intraoperative/postoperative ephedrine requirements , postoperative nausea and vomiting and the duration of stay in PACU were evaluated. Results: In group S, intraoperative blood loss was 203.00±108.73 ml, while in group G it was 198.00±106.40. There were no statistically difference between the groups (p=0.884). Inthe duration of surgery, amount of fluid given intraoperatively, intraoperative ephedrine requirements was compared, there wereno difference between the groups too (p=0.085, p=0.056 and 0.448, respectively). Conclusion: In this study, it was shown that general and spinal anesthesia did not affect major parameters such as intraoperative bleeding in patients undergoing.Öğe The relationship between preoperative and postoperative neutrophil-lymphocyte and platelet-lymphocyte ratio with post-dural-puncture headache in patients undergoing cesarean section(2019) Sargin, Mehmet; Uluer, Mehmet Selcuk; Tutar, Mahmut SamiAim: This study aims to evaluate whether there is a possible relationship between the preoperative and early postoperative period neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio and post-dural-puncture headache in patients undergoing cesarean section.Material and Methods: Two hundred twenty pregnant women scheduled to undergo elective cesarean section under spinal anesthesia, were studied. Patiens demografic data and blood count parameters were noted. Blood was sampled from a peripheral vein for neutrophil/lymphocyte ratio ve platelet/lymphocyte ratio. The time points for sampling blood were as follows: Preoperative; 1 day before and postoperative; within 6-12 hours after cesarean section. The patients were questioned for possible occurrence of spinal anesthesia induced headache on the first and seventh postoperative days. Post-dural puncture headache was evaluated according to the International Classification of Headache Disorders (ICHD-II) diagnostic criteria.Results: A total of 220 patients were enrolled in the study and 217 patients completed the investigation. Post-dural puncture headache was detected in 78 patients and the incidence was 35.9%. The measurements of laboratory parameters were statistically similar between two groups (P > 0.05).Conclusion: Our study results showed no relationship between the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio, and post-dural-puncture headache in the preoperative and also, early postoperative period in patients who undergoing cesarean section.Keywords: Post-Dural-Puncture Headache; Neutrophil-Lymphocyte Ratio; Platelet-Lymphocyte Ratio; Cesarean Section.
